Hi Carlitos, thanks for being interested in my build
About the gold wrap, I didn't do any testing of before and after for air temp as my obd2 port is locked and the tuner didn't unlock it, also, I am lazy to go back to him to unlock it
I used a 30x2 tape that I got from my friend (he used no more than 6 inches) and it was enough to wrap the intakes from throttle to the line of radiators. Another friend is installing intakes on his G37 currently and have a full 30x2 tape and I can check how much he will use.
